SHUTTLE FOR 'WEET-REFLENISHING LGOMS.

Be it known that I, FRED ARNOLD MAN- CHESTER, of Ho-pedale, in thecounty of Worcester and State of Massachusetts, have invented a new anduseful lmprovement in Shuttles for Wett-Replenishing Looms, of --whichthe following is a specification. i,

The present invention relates to a spreader employed to maintain in:proper relative position the holding jaws 'of the shuttle sprin which isemployed in automatically threading shuttles for the purpose ofyieldingly grasping the head of the bobbin or other analogous weftcarrier.

The improvement is illustratedin the accompanyiug drawings, in which-Figure l, is a plan view lof the weft carrier holding end of a shuttle,parts being broken away to facilitate the illustration. Fig. 2, is alongitudinal vertical section of the same end of the shuttle. Fig. 3, isa' cross-section. Fig. 4, is an enlarged horivline i- 4 in Fig. 2.

The improved spreader is intended to keep in proper position lthe twojaws of the the jaws are bent from a single piece of sheet metal so thatthe jaws are maintained at the proper 'distanceapart to receive anautomatically inserted weft-carrier and to securely hold the same inplace. i Suche panying drawings, whereinl,

A, is the shuttle, B, is theshuttle spring,

has resilient jaws a, a, and a shank consisting of two connected vlegsb, b, which fit shuttle. rlhe guard C, embraces the shankof the shuttlespring and is maintained in place by a screw D. The shuttle spring iStransverse bolt` E, passing transverselyA through both legs of theshank.l ln all of the respects just described, ythe shuttle spring andits guard are similar to corre- The present improvement4 resides in thevpassing through `apertures in the upper and lower plates c, and d, ofthe 'shuttle guard.

rspreader so that the upper surface. of the bolt headis flush with theupper surface of the guard. This spreader extends vertically between thelegs b, and b, as shown in Fig. Il, and its cylindrical body fitstightly against the facing surfaces of said legs.

' There is no lost motion between the spreader and the legs of theshuttle spring shank and, consequently,j thefree jaws a, a, of theshuttle spring are held the proper distance apart so` that they cannotapproach each other suiiiciently .to prevent theready entrance of thehead of the automatically inserted weft-carrier.

The spreader has a nick in its head to receive a screw-driver for thepurpose of inserting and withdrawing the spreader from its nut G.

I claimi'-l i x l. A shuttle for weft replenishing looms having ashuttle spring with a shank consisting of separated legs fitting withina recess in the shuttle body, a guard having upper and lower platesembracing the shank of the shuttle spring, said upper and lower 'plateshaving apertures that in the upper plate being conical, a spreaderconsisting of a vertical bolt whose. cylindrical body tits tightlybetween the legs of the shuttle spring shank said bolt passing throughthe apertures in the upper and lower plates of the guard, said bolthaving a conical head litting within the conical aperture of` the upperplate ofthe guard and being screwthreaded at its lower end, 4and`a nutlocated within a socket in the bottom of the shuttle into which thelower end of the bolt screws.`

2. A shuttle for weft replenishing looms having a shuttle spring with ashank con-` sisting of separated legs fitting within a recess in theshuttle body, a guardhaving upper and lower platesembracing thev shankof the shuttle spring, said upper and lower plates havin apertures, aspreader consisting of avertical bolt fitting tightly between the legsof the shuttle spring shank and `i'passing through the apertures in theupper and lower plates of the guard, and a nut located within a socketin the bottom of the shuttle into which the lower end of the spreaderbolt screws.

3. A shuttle for weft replenishing looms having a shuttle spring with ashank consisting of sepanated legs, a spreader Consisting of a verticalbolt fitting tightly between the legs of the shuttle `spring shank, anda nut located within a-sooket in the bottom of the shuttle into whichthe lower end of the spreader bolt screws.

4. A shuttle for weft replenishing looms having a shuttle spring with ashank con sisting of separated legs, a guard having upper and lowerplates embracing the shank of the shuttle spring, said upper -'and lowerplates having apertures in the upperv plate being beveled, and aspreader fitting tightly between the legs of the shuttle spring shankand passing through the apertures in the upper and lower plates of theguard.

5. A shuttlefor weft replenishing looms having a shuttle spring wit-h ashanl; Con-I its lower end, and a nut located within a socket in thebottom of the shuttle into which the lower end of the spreader boltscrews.
